[Masonite division of International Paper Co] A registered trademark for a type of hardboard building material first made in 1924 by William H. Mason. Masonite® is a wet process Fiberboard composed of fine wood fibers compressed into a dense, rigid sheet with heat. The fibers are held together by the natural binders from the pulp with no additional adhesive. Masonite® boards do not bend or warp easily but the sheets are brittle and break under pressure. Standard Masonite® Presdwood® is brown in color with one very smooth surface; the reverse side has a wire screen impression. Some artists have coated the rough surface with gesso and used it as a painting support. Tempered Presdwood® is prepared with an oil that adds weather resistance to the board, but makes it less receptive to Paint or Gesso.
